The term "astronaut" derives from the Greek words meaning "space sailor," and refers to all who have been launched as crew members aboard NASA spacecraft bound for orbit and beyond. Since the inception of NASA's human space flight program, we have also maintained the term "astronaut" as the title for those selected to join the NASA corps of astronauts who make "space sailing" their career profession. ...

... Figure 2 : NGC 7052 HST images . ... MPG Movie : Animation of stellar motions around black hole in M32 . Massive BHs are thought to be responsible for the energy production in active galaxies, and are believed to be common in quiescent galaxies as well. Dynamical evidence for this can be sought by studying the kinematics of stars and gas in galactic nuclei. In the 1970's M87 was the first galaxy for which stellar kinematical data hinted at a BH, but not conclusively. ...

Based on the measurements of the Stokes parameters in the continuum and in the broad 0.6563 nm hydrogen emission line obtained with the 6-m telescope for the Seyfert galaxy Mkn 6, secular variability of the hydrogen line profile polarization was discovered; a time lag of less than 2 days between the continuum flux and the polarized continuum emission was determined which corresponds to the size of the region where the polarization of the continuum occurs, less than 0.001 pc. ...

We investigate the relative importance of starbursts and active galactic nuclei (AGN) in nuclear activities of ultraluminous infrared galaxies (ULIRGs) based on chemodynamical simulations combined with spectrophotometric synthesis codes. We numerically investigate both the gas accretion rates (ARs; m acc ) on to supermassive black holes (SMBHs) and the star formation rates (SFRs; m sf ) in ULIRGs formed by gas-rich galaxy mergers and thereby discuss what powers ULIRGs. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
